ExaGrid White Papers The Benefits of Second Generation Disk-based Backup Technology
Overcoming the Challenges of Tape with a Disk-Based Backup Solution All organizations use tape to back up data nightly. Tape is fairly inexpensive and low-tech, but managing and administering tape, backing up to tape and restoring files from it can be time consuming, unreliable and complex. Disk has always been an easier, more reliable alternative, but until recently its high acquisition cost has made it untouchable for many organizations. Fortunately, new disk and data reduction technologies have recently converged to make disk-based backup available at about the same price of tape backup systems. This white paper examines the pros and cons of both technologies and will present a cost analysis of ExaGrid’s disk-based backup system with data de-duplication and compression vs. tape and standard SATA disk.
Data De-duplication MethodologiesComparing ExaGrid's Byte-Level Data De-duplication to Block Level Data De-duplication Though data de-duplication technologies have been around for years, there is a renewed focus on them recently as they are being utilized by products in the disk-based backup market. Data de-duplication enables disk to be a feasible long-term retention backup media -- making it the same or lower cost than tape-based systems.
Disk-based Data Protection OptionsThe Changing Data Protection Landscape The rapidly falling cost of SATA disk has come closer to the cost of magnetic tape, making it a viable option for data center backup. While standard SATA is at the core of many D2D backup processes, there are several options to weigh when making the move to a complete disk-based backup solution. This white paper will help you learn how to take advantage of the changing backup landscape.
Major Considerations in Moving to Disk-based Backups Moving Beyond Magnetic Tape Disk-based backup resolves many traditional tape backup problems. But, using standard disk alone creates other challenges, especially when longer term retention is required. This white paper will help you learn the key considerations for a successful, cost-effective disk-based backup solution.
Five Key Considerations for Evaluating the Scalability of Disk-based Backup SolutionsIn selecting a disk-based backup solution, it's critical to consider the scalability of each prospective solution to ensure that it will meet the needs of your organization now and into the future. This paper outlines the five key questions you should ask when evaluating the scalability of any disk-based backup solution.
